Cataract Surgery in Omaha, Nebraska
Personalized cataract surgery by Dr. Ivey L. Thornton, MD — Board-Certified Ophthalmologist, fellowship-trained in anterior segment surgery.
One of the safest, most refined procedures in modern medicine — tailored to your eyes, your life, and the vision you actually want after. Cataract surgery Omaha patients receive at the Truhlsen Eye Institute is performed by fellowship-trained surgeons with hospital-based safety standards.
When the world begins to soften.
Cataracts are a natural clouding of the eye’s internal lens. They develop gradually, often over years, which is why patients describe the change as “the world looking washed out” or “the brightness disappearing” more than any single moment of blur.
They are one of the leading causes of vision loss worldwide — and also one of the most successfully treated. Modern cataract surgery is an outpatient procedure performed in under twenty minutes per eye, with vision typically restored within days. The technology, the implant options, and the surgical precision available today would have been unimaginable a generation ago.
What hasn’t changed is that every eye is different. Dr. Thornton spends more time in cataract consultations explaining what each patient’s vision could be after surgery than most surgeons spend in the operating room. Personalized lens selection is the heart of a good outcome.
Symptoms of cataracts.
Cataracts can develop silently. The most common symptoms patients describe:
- Cloudy, blurry, or dim vision
- Colors appear faded, especially reds, blues, and yellows
- Increased sensitivity to glare — bright sunlight, oncoming headlights
- Halos or starbursts around lights at night
- Needing more light to read comfortably
- Frequent prescription changes for glasses or contacts
- Double vision in one eye
- Poor contrast — difficulty reading fine print or distinguishing similar colors
If several of these sound familiar, a comprehensive eye exam including a slit lamp evaluation can confirm whether cataracts are the cause — or whether another condition (such as early macular degeneration) may be contributing.
When to consider cataract surgery.
There’s no “right” time on a calendar — the right time is when the cataract is meaningfully affecting your daily life. Some patients notice difficulty driving at night first. Others notice when reading small type or recognizing faces becomes harder. Either is a valid reason to consider surgery.
Surgery is also considered when a cataract is interfering with the evaluation or treatment of other eye conditions (for instance, when a dense cataract makes it impossible to monitor diabetic retinopathy or macular degeneration). In those cases, the surgery is more than cosmetic — it restores the ability to manage overall eye health.
Dr. Thornton will not recommend surgery until it will meaningfully improve your vision and quality of life. If a cataract is small and not yet interfering with what you do, watchful monitoring is often the right answer.
Intraocular lens (IOL) options.
Cataract surgery replaces the cloudy natural lens with a clear synthetic intraocular lens. Lens choice is where personalization matters most — and Dr. Thornton walks every patient through the trade-offs of each option.
Monofocal IOL
Single fixed focal distance — usually set for clear distance vision. Reading glasses typically needed. Covered by most insurance and Medicare.
Toric IOL
A monofocal IOL with built-in astigmatism correction. Reduces dependence on glasses for distance. Premium upgrade from standard IOL.
Multifocal IOL
Multiple focal points in one lens for distance, intermediate, and near vision. The most glasses-independence; some patients notice halos at night.
EDOF (Extended Depth of Focus) IOL
A continuous range of clear vision from distance through arm’s length. Often the best balance between glasses-independence and visual quality at night.
Accommodating IOL
A lens designed to shift position inside the eye with natural focusing effort — providing some near vision without the rings of a multifocal.
Monovision
One eye optimized for distance, the other for near. Not an IOL type but a strategy — often used when patients have tolerated monovision contact lenses successfully.
What to expect during cataract surgery.
Before surgery
A comprehensive pre-operative exam including biometry (precise measurements of the eye used to calculate the IOL power), endothelial cell evaluation, macular OCT, and detailed discussion of IOL options. This appointment typically takes 90 minutes. Dilating drops are used; arrange for someone to drive you home.
The procedure
Cataract surgery is performed as an outpatient procedure at the Truhlsen Eye Institute in Omaha. Anesthetic eye drops and mild sedation keep you comfortable — no general anesthesia. A tiny incision (about 2-3mm) is made; the cloudy lens is broken up with ultrasound (phacoemulsification) and removed; the new IOL is folded and inserted through the same incision where it gently unfolds into place. The procedure takes 15 to 20 minutes per eye.
Recovery
You’ll be monitored briefly and then go home the same day with a protective shield to wear overnight. Most patients notice improved vision within a day or two; final stabilization takes 4-6 weeks. Follow-up appointments are at 1 day, 1 week, and 1 month post-op. Prescription eye drops are used for a few weeks. The second eye is typically operated on 1-2 weeks after the first.
Combining cataract surgery with refractive correction.
Patients who have had LASIK or PRK in the past can still have cataract surgery — the biometry is more complex but the outcome is the same. Dr. Thornton uses specialized formulas for post-LASIK eyes to calculate IOL power precisely.
For patients over 45 who are considering refractive surgery AND are developing early cataracts, Refractive Lens Exchange (RLE) may be the better approach — replacing the natural lens with a premium IOL addresses both refractive error and any future cataract in a single procedure. Dr. Thornton offers RLE as part of her refractive surgery practice at the Refractive Surgery Alliance.
Frequently asked questions.
Is cataract surgery painful?
No. Numbing drops and mild sedation keep you comfortable. Most patients describe mild pressure but no pain. The eye may feel scratchy or gritty for a few hours afterward, which prescription eye drops manage.
How long does cataract surgery take?
The surgery itself takes 15-20 minutes per eye. Including pre-op preparation and post-op monitoring, plan to be at the surgery center for about 2 hours.
Is cataract surgery covered by insurance?
Yes. Medicare and most commercial insurance plans cover standard cataract surgery with a monofocal IOL. Premium IOLs (toric, multifocal, EDOF) have an out-of-pocket upgrade cost — Dr. Thornton’s team will walk you through the specifics for your insurance.
Can both eyes be done at once?
No. Standard practice is to operate on one eye at a time, typically 1-2 weeks apart. This allows the first eye to heal and gives Dr. Thornton the chance to refine the IOL calculation for the second eye based on the first outcome.
How soon can I drive after surgery?
Most patients are cleared to drive within a few days, once vision is stable and the operative eye is comfortable. The day of surgery, you’ll need someone to drive you home.
Will I still need glasses after cataract surgery?
It depends on the IOL chosen. Monofocal IOLs typically leave patients needing reading glasses. Premium IOLs (multifocal, EDOF, accommodating) substantially reduce or eliminate glasses dependence. Dr. Thornton will walk you through realistic expectations based on your anatomy and lifestyle.
What is a “secondary cataract”?
Sometimes the capsular bag holding the new IOL becomes cloudy months or years after surgery — this is called posterior capsular opacification (PCO), informally “secondary cataract.” It’s not a true cataract and is easily treated with a painless 2-minute laser procedure (YAG capsulotomy) in the office.
Is the new lens permanent?
Yes. Modern IOLs are designed to last a lifetime inside the eye. Unlike the natural lens, they don’t develop cataracts or change clarity over time.
About Dr. Thornton as a cataract surgeon.
Dr. Ivey L. Thornton is Board-Certified by the American Board of Ophthalmology and fellowship-trained in anterior segment surgery at the Cincinnati Eye Institute — one of the most prestigious cataract and refractive surgery fellowships in North America. She completed a second fellowship at Harvard in neuro-ophthalmology.
She has performed cataract surgery for since 2011 and teaches anterior segment surgical technique to residents at UNMC through a research collaboration with Nebraska Medicine. Her practice emphasizes personalized IOL selection — understanding that the right lens for one patient is often the wrong lens for another.
What patients consistently describe is how much time she spends explaining — before surgery, during recovery, and at every follow-up. If you don’t understand what’s happening to your eyes, she hasn’t done her job.
